If you're seeing this, you've probably stubmled upon one of my automatically generated payloads for the responsible disclosure or bug bounty program.
This is not a social engineering or phishing test. The objective of this test is to check for Blind XSS in a privileged environment.
This test is harmless and does not log any confidential information other than the URL's that could potentially be vulnerable to blind XSS.
If your enviroment is vulnerable to it, I will inform your security team about it, so they can fix it.
If you have any questions, you may always contact inti [at] @ inti (dot) io. I will do my best to answer your question as soon as possible.
